S/2003 J 23

Imagine a tiny speck of dust, but way out in space! That's kind of like S/2003 J 23. It's a moon, which means it's a small space rock that goes around a much bigger planet. This moon is super small, only about 2 kilometers (1 mile) wide. That's shorter than a big skyscraper! It's so small that it's hard to even see.

S/2003 J 23 is a friend of Jupiter, the biggest planet in our solar system. Jupiter is so huge, it's like a giant beach ball compared to a tiny pea! This little moon orbits Jupiter really, really fast. It takes less than one Earth day to go all the way around its giant planet friend. That's faster than you can run around a playground!

This moon is part of a big family of moons that circle Jupiter. Jupiter has lots and lots of moons, more than 90! S/2003 J 23 is one of the smallest and furthest away from Jupiter. It's like being in the very last row of a giant stadium, far from the action.

Scientists found S/2003 J 23 in 2003 using powerful telescopes. These telescopes are like super-powered eyes that can see things very far away in space. They spotted this little moon hiding in the dark, going around Jupiter. It's amazing what we can discover when we look up at the stars!
